Applying Membrane Processes to Groundwater Sources for Trihalomethane Precursor Control

The use of membrane processes for controlling trihalomethanes (THMs) was investigated for Florida groundwater sources and one surface water source. All of the sources were used for public supply and had excessive THMs (>300 μg/L) in the finished water. The performance and projected cost of the membrane system using groundwater sources are reported in this article.
